>Description:
When using the configuration options EXAMPLES=on and GOST=off, the port will not build.
This is due to the 'post-configure' section in the WITH_EXAMPLES if block.

post-configure:
        @(cd ${WRKSRC}/examples; ./configure --prefix=${PREFIX} \
                --infodir=${PREFIX}/${INFO_PATH} --mandir=${MANPREFIX}/man \
                --build=${CONFIGURE_TARGET})

This section does not use the CONFIGURE_ARGS defined for the else block of WITH_GOST.

.if defined(WITH_GOST)
BUILD_DEPENDS+= openssl>=1.0:${PORTSDIR}/security/openssl
.else
CONFIGURE_ARGS+=        --disable-gost
.endif

If I manually edit the makefile and add '--disable-gost' to the post-configure block above, I can successfully build the port with EXAMPLES enabled and GOST disabled. I am not, however, sure how to include CONFIGURE_ARGS in the post-configure block appropriately (due to my inexperience with the ports makefile system).
>How-To-Repeat:
cd /usr/ports/dns/ldns
make config
# enable EXAMPLES
# disable GOST
make
>Fix:
Add CONFIGURE_ARGS to the post-configure block in the WITH_EXAMPLES section. The '--disable-gost' configuration argument is not being propagated to the nested configure invocation.
